✅ Product Introduction
The Bently Nevada 3500/32M Relay Module (Part Number: 184704-01) is a 4-Channel Relay Output Module designed for use in the 3500 Machinery Protection System. This module provides independent, programmable alarm outputs, each capable of being configured with logical voting, latch functions, and fail-safe or non-fail-safe operations.
It acts as a hardware interface between the monitoring rack and external control systems such as shutdown circuits, alarms, or interlocks. This module is essential for turning monitored alarm conditions into real-world actions like equipment shutdown or process control triggers.

❓ FAQ – Top 10 Questions (QA Format)
Q1: What is the main purpose of the 3500/32M module?
A1: The 3500/32M outputs relay signals based on configured alarm conditions, enabling machinery shutdown, alarms, or interlock operations.
Q2: Can each relay channel be configured independently?
A2: Yes, all four channels are fully independent and programmable with unique logic and trip conditions.
Q3: Is this module hot-swappable?
A3: No, it’s recommended to power down the rack before installing or removing the module.
Q4: What kind of loads can the relays drive?
A4: The relays can handle up to 5A at 24VDC or 240VAC for resistive loads. Inductive loads require proper suppression.
Q5: How is logic configured for the relay outputs?
A5: Logic is configured using the 3500 configuration software. You can assign AND/OR/VOTE/LATCH functions to each output.
Q6: Is this module safe for hazardous area installations?
A6: Yes, when properly installed, it supports use in Zone 2 and Division 2 hazardous environments with corresponding certifications.
Q7: What is the relay response time?
A7: Response time is very fast, typically in milliseconds, depending on system logic and alarm processing.
Q8: How can I verify if a relay is working?
A8: Check the module’s LED indicators, monitor status via the TDI, and use test functions in the configuration software.
Q9: How long do the relays last?
A9: Under rated conditions, relay life is typically over 100,000 switching cycles.
Q10: Can I use multiple 32M modules in one system?
A10: Yes, systems can include several 32M modules to increase relay output capacity or create redundant output configurations.
